Server Sky - Internet and Computation in Orbit

DC L5, June 30, 2013

Server sky is a proposal to build large arrays of 5 gram paper-thin solar-powered computer satellites in 6400km earth orbit. Arrays act as large parallel computers and phased array antennas, transmitting thousands of communication beams simultaneously to low cost ground receivers and other arrays in space.

U.S. data centers consume 10GW of electricity to produce microwatt signals delivered to customers. Converting space solar power into computation and sending the only results eliminates most of the cost and mass of SBSP, as well as the expense and inefficiencies of data centers and fiber optic infrastructure. Server sky can provide high reliability broadband internet to developing nations with much lower economic and environmental cost.
